From 62902ca45de871aa59657dd8ec1858c301595634 Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Tue, 29 Nov 2016 14:13:43 +0100 Subject: sb/ich7: Use common/gpio.h to set up GPIOs This is more consistent with newer Intel targets. This a static struct so it is initialized to 0 by default. To make it more readable: * only setting to GPIO mode is made explicit; * only pins in GPIO mode are either set to input or output since this is ignored in native mode; * only output pins are set high or low, since this is read-only on input; * blink is only operational on output pins, non-blink is not set explicitly; * invert is only operational on input pins, non-invert is not set explicitly.
